Since winter is quickly approaching, the furnaces in our homes will be in frequent use. Around this time of year, we receive many calls about a wide variety of issues regarding furnaces and heaters. Some problems are easily solvable, while others might require a more comprehensive examination. Our HVAC specialists in Tulsa have identified the most common problems and their potential causes.

Furnace Won’t Turn On

This issue depends on the age of your unit and if it receives regular maintenance. Check to see if the thermostat is set to “heat,” and if issues persist, you might have to replace the batteries or purchase a new thermostat altogether. Inspect your circuit breaker to see if any circuits are tripped or blown. Verify if your pilot light is malfunctioning.

Furnace Blowing Cold Air/Not Enough Heat

Inspect the air filters in your furnace. A dirty filter prevents air to flow throughout your entire house properly and should be replaced every one to three months. Insufficient insulation, such as worn seals and cracks in your ductwork can allow heated air to escape. If you’re experiencing an uneven airflow, the design of your ductwork might not be adequate enough to disperse air throughout your home, or it doesn’t correspond with your current heating system.

Furnace Frequently Runs for Short Intervals

If your thermostat is located near a heating vent, the furnace will turn on once the warm air flows to colder rooms. A furnace will become active when the temperature in your home dips below what’s set. Ensure the thermostat is somewhere away from the vents so it can accurately read the temperature of the entire house. Your home might be leaking air, causing your furnace to run more periodically than it should. Perhaps, your furnace is overheating due to poor ventilation.
